[dpdk-dev] [RFC 00/17] unified packet type

[dpdk-dev] [RFC 00/17] unified packet type

[Helin Zhang]

Currently only 6 bits which are stored in ol_flags are used to indicate
the packet types. This is not enough, as some NIC hardware can recognize
quite a lot of packet types, e.g i40e hardware can recognize more than 150
packet types. Hiding those packet types hides hardware offload capabilities
which could be quite useful for improving performance and for end users.
So an unified packet types are needed to support all possible PMDs. Recently
a 16 bits packet_type field has been added in mbuf header which can be used
for this purpose. In addition, all packet types stored in ol_flag field
should be deleted at all, and 6 bits of ol_flags can be save as the benifit.

Initially, 16 bits of packet_type can be divided into several sub fields to
indicate different packet type information of a packet. The initial design
is to divide those bits into 4 fields for L3 types, tunnel types, inner L3
types and L4 types. All PMDs should translate the offloaded packet types into
this 4 fields of information, for user applications.

As the changes affect all PMDs, mbuf and ethdev library, comments and ideas
are welcome!

[dpdk-dev] [RFC 01/17] mbuf: add definitions of unified packet types

[Helin Zhang]

As there are only 6 bit flags in ol_flags for indicating packet types,
which is not enough to describe all the possible packet types hardware
can recognize. For example, i40e hardware can recognize more than 150
packet types. Unified packet type is composed of tunnel type, L3 type,
L4 type and inner L3 type fields, and can be stored in 16 bits mbuf
field of 'packet_type'.

[dpdk-dev] [RFC 17/17] mbuf: remove old packet type bit masks for ol_flags

[Helin Zhang]

To unify packet types among all PMDs, bit masks and relevant macros
of packet type for ol_flags are replaced by unified packet type and
relevant macros.

I still think it would be better to use enum not bit-set for IPv4/IPv6 distinction, but if you set it that way,
can you at least take advantage of it and make RTE_ETH_IS_IPV4_HDR() not require 3 comparisons?
I think it is doable if you set bit 4 for IPv4 types only (you already do that)
and bit 6 for IPv6 types only.
For that, I think, you can make RTE_PTYPE_L3_IPV4_EXT_UNKNOWN == 0xb0  /* 0b0000000010110000 */
Then you can:

#define  RTE_ETH_IS_IPV4_HDR(ptype)    (((ptype) & RTE_PTYPE_L3_IPV4) != 0)
#define  RTE_ETH_IS_IPV6_HDR(ptype)    (((ptype) & RTE_PTYPE_L3_IPV6) != 0)

I suppose that would be faster then what you propose below,
and would probably require less changes in our sample apps.

This seems a bit sparse, in that the protocol field is 8 bits wide in a packet.
There are several common protocls that you don't have listed, and you've already
exhausted your namespace with the list you have.

Another question I've asked several times[1][2] : what does having
RTE_PTYPE_TUNNEL_IP mean? What fields are checked by the hardware
(or the driver) and what fields should be checked by the application?
Are you sure that all the drivers (ixgbe, i40e, vmxnet3, enic) check
the same fields? (ethertype, ip version, ip len correct, ip checksum
correct, flags, ...)

To be clearer: Let's say I have a network stack that parses and
validates an IP packet. What tests can I remove if I get
RTE_PTYPE_TUNNEL_IP?

This question can be asked for all defined packet type. To be usable by
an application, I think a formal definition would be needed. This is
also important to know this for people wanting to develop a new PMD
based on a new hardware. If the hardware does not behave exactly like
ixgbe, i40e (I hope all drivers you implemented behave exactly the
same), some work has to be done in the driver or the feature cannot be
used.

One naïve question: are we sure that at the end, using these complex
packet types is faster than parsing the packet?

Regards,
Olivier

Thats an excellent question, especially when you start considering that high
layer stack functions will want to isolate themselves from these complex packet
types.

I have reviewed all packet types supported in igb, ixgbe and i40e, and read the
code to get the packet types used in vmxnet3, bond, enic ,etc.
Current design can support all packet types used in above PMDs.
Yes, we don't have too many space reserved for future, but we can try to make
more bits for packet_type field later, as we can save 6 bits in ol_flags with this
patch set.

RTE_PTYPE_TUNNEL_IP means hardware recognizes the received packet as an
IP-in-IP packet.
All the fields are filled by PMD which is recognized by hardware. The application
can just use it which can save some cpu cycles to recognize the packet type by
software.
Drivers is responsible for filling with correct values according to the packet types
recognized by its hardware. Different PMDs may fill with different values based on
different capabilities.

That means it is a IP-in-IP tunnel packet, but not others. Also you can check other
fields in packet_type to get more information of the packet (e.g. L4 type).

The unified packet type defined here is aiming to support all hardwares. I40e has
different values from ixgbe. We can add more in the future if needed for future NICs.

I guess yes for almost all cases, as hardware reported the packet types, and PMD
just puts the correct values into packet_type field.
Later, we will try to measure the differences.

As waste of one bit can support Vector PMD well, I prefer to have it here.
Thank you very much for the good idea of bit selection, to get possible higher
performance. I will add the idea in the next version. Thanks a lot!

Re: [dpdk-dev] [RFC 01/17] mbuf: add definitions of unified packet types

Sorry, that does not answer to my question.

Let's take a simple example. Imagine a hardware-1 that is able to
recognize an IP packet by checking the ethertype and that the IP
version is set to 4.
Another hardware-2 recognize an IP packet by checking the ethertype,
the IP version and that the IP length is correct compared to m_len(m).

For the same packet, both hardwares will return RTE_PTYPE_L3_IPV4, but
they don't do the same checks on the packet. As I want my application
behave exactly the same whatever the hardware, I need to know what
checks are done in hardware, so I can decide what checks must be
done in my application.

Example of definition: RTE_PTYPE_L3_IPV4 means that ethertype is
0x0800 and IP.version is 4.

It means that I can skip these 2 tests in my application if I have
this packet_type, but all other checks must be done in software
(ip length, flags, checksum, ...)

For each packet type, we need a definition like above, and we must
check that all drivers setting a packet type behave like described.

Olivier
